Destroyer Isonami

Isonami was a Fubuki-class destroyer laid down at Uraga Dock Company in October 1926, launched 24 November 1927, and commissioned 30 June 1928. She participated in the invasion of Malaya and the Dutch East Indies in December 1941–March 1942, serving as escort for troop convoys and participating in surface actions. After taking part in the Battle of Midway and transport runs in the Solomons and New Guinea in 1942, Isonami was reassigned in February 1943 to the Southwest Area Fleet, based at Surabaya, for convoy escort duties in the Dutch East Indies. On 9 April 1943, while escorting a convoy from Surabaya to Ambon, Isonami was torpedoed by the U.S. submarine USS Tautog (SS-199) as she rescued survivors of the torpedoed Penang Maru. She sank about 35 nautical miles southeast of Wangiwangi Island, off southeastern Celebes (Sulawesi), at approximately 5°26′S 123°04′E; seven of her crew were killed. Her loss highlighted the growing threat posed by U.S. submarines to Japanese supply lines in the Dutch East Indies.
